No longer true.
At least since Zen 3 (2020), all AMD desktop Ryzen CPUs have ECC support clearly included in their specifications, so it is official support, not just a non-disabled ECC.
This change was around the same time when Intel has begun to support ECC in some Alder Lake desktop CPUs (and in their successors), so it might have been a response to Intel's decision.
So now the ECC support depends strictly on the motherboard manufacturer. The best chance to find motherboards with ECC support is at ASUS and at ASRock (including ASRock Rack, which offers server boards for Ryzen CPUs).
